Re: [PATCH v7 0/5] Update LZ4 compressor module

Also I noticed another bug, this time in LZ4_count():

> #if defined(CONFIG_64BIT)
> #define LZ4_ARCH64 1
> #else
> #define LZ4_ARCH64 0
> #endif
...
> #ifdef LZ4_ARCH64

>        }
> #endif

Because of how LZ4_ARCH64 is defined, it needs to be '#if LZ4_ARCH64'.

But I also think the way upstream LZ4 does 64-bit detection could have just been
left as-is; it has a function which gets inlined:

	static unsigned LZ4_64bits(void) { return sizeof(void*)==8; }
